Strong surface winds in Storm <i>Eunice</i>. Part 2: airstream analysis

Abstract

Storm Eunice caused severe wind impacts on the United Kingdom on 18 February 2022. This article contains the second of a two-part study and consists of a detailed analysis of Eunice's airstream structure, confirming the presence of sting-jet (SJ) activity during its lifecycle. By the time Eunice crossed Wales and southern England, several other airstreams, including a cold conveyor belt and a dry intrusion, interacted in generating the observed damaging winds. These results illustrate the wind-damage potential of multiple airstreams, including SJs, in intense cyclones like Eunice (as displayed in the figure), highlighting the importance of accurate airstream forecasts.
